Abstract

L'invention concerne un dispositif de protection (1) contre les surtensions comportant : - un circuit imprimé (9), - une varistance (21) présentant un corps de varistance en oxyde métallique qui présente une face (25) et une couche métallique (28) conductrice déposée sur ladite face (25), dans lequel la varistance (21) est reliée à une première borne de connexion (2) électrique par une première piste de connexion (10) du circuit imprimé et une patte de déconnexion (24), la patte de déconnexion (24) étant directement fixée à la couche métallique (28) par une liaison thermofusible et exerçant sur ladite couche métallique (28) une force de traction de sorte que la patte de déconnexion (24) s'écarte de la couche métallique (28) et coupe la connexion électrique entre la première borne (2) et la varistance (21) en réponse à une fusion de la liaison thermofusible.
